好吧,这开始让我爬上墙,我无法做到这一点,所以希望有人可以提供帮助!
我使用的是Symfony 2.3,我在’UserType’类中构建了我的用户表单.我有两个地方,一个是应用程序添加新用户时,我希望该字段保持不变.但是我构建了一个新的“UserType”来查看所有用户,因此将app作为管理区域.
因此,我希望能够在我的用户表单上删除我的密码输入中的“必需”,当表单刚刚编辑时,例如电子邮件已更新.
从我所读到的,这在树枝上是不可行的(我不明白为什么!)但我必须在建造者中做到这一点?
1,有没有办法在树枝上做到这一点,最好的选择!
2,我如何只对我的一个’UserTypes’而不是另一个?
所以我的代码如下,
UserType.php
public function buildForm(FormBuilderInterface $builder, array $options) {
$RoleOpts = ['ROLE_USER' => 'User','ROLE_ADMIN' => 'Admin'];
$builder->setMethod('POST');
$builder->add('username', 'text', ['label' => 'Username', 'attr' => ['autocomplete' => 'off','class' => 'Admin_Username']]);
$builder->add('password', 'password',['label' => 'Password', 'attr' => ['autocomplete' => 'off','class' => 'Admin_Pswd']]);
$builder->add('firstname', 'text', ['label' => 'First Name','attr' => ['autocomplete' => 'off','class' => 'Admin_Name']]);
$builder->add('surname', 'text', ['label' => 'Surname', 'attr' => ['autocomplete' => 'off','class' => 'Admin_Surname']]);
$builder->add('email', 'email', ['label' => 'Email', 'attr' => ['autocomplete' => 'off','class' => 'Admin_Email']]);
$builder->add('userroles', 'choice', ['label' => 'Role','choices' => $RoleOpts, 'attr' => ['class' => 'Admin_Role']]);
$builder->add('save', 'submit', ['label' => 'Save User', 'attr' => ['class' => 'Admin_SaveUser']]);
}
ViewUsers Action
public function ViewUsersAction() {
$GetAllUsers = $this->getDoctrine()
->getRepository('Bundle:Users')
->findAll();
foreach($GetAllUsers as $UserKey => $UserValue) {
$UserID = $UserValue->getId();
$ViewAllUsers[$UserKey] = $this->createForm(new UserType(),
$GetAllUsers[$UserKey],
['action' => $this->generateUrl('Admin_EditUser', ['id' => $UserID])]
)->createView();
}
return $this->render('Bundle:Admin:Users/view.html.twig', ['ViewUsers' => $ViewAllUsers ]);
}
树枝文件
{% for View in ViewUsers %}
{{ form_start(View, {'attr': {'class': 'EditUser'}}) }}
{{ form_errors(View) }}
{{ form_row(View.username, {'attr': {'disabled': 'disabled'}}) }}
{{ form_row(View.password, {'attr': {'required': false}}) }}
{{ form_row(View.firstname) }}
{{ form_row(View.surname) }}
{{ form_row(View.email) }}
{{ form_row(View.userroles) }}
{{ form_row(View.save, { 'label': 'Update User' }) }}
{{ form_end(View) }}
{% endfor %}
我已阅读,Force a field to not be required,但是它将它添加到构建器,这将更改添加新用户,并编辑所有用户,这是我不想要的!
有什么帮助吗?

最佳答案 第一步是在setDefaultOptions方法中编写默认选项.
第二步是使用buildForm方法中的选项:
class UserType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
// ...
$builder->add('password', 'password',['required' => $options['password_required']]);
}
/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\User',
'password_required' => TRUE
));
}
/**
* @return string
*/
public function getName()
{
return 'appbundle_user';
}
}
第三步是从editAction或createEditForm方法(或者在你的情况下是你的ViewUsersAction)调用createForm方法,使用额外的选项’password_required’=>假:
$form = $this->createForm(new UserType(), $entity, array(
'action' => $this->generateUrl('user_update', array('id' => $entity->getId())),
'method' => 'PUT',
'password_required' => FALSE
));
